Buster Bear in "Little Joe Otter Supplies Buster Bear With A Breakfast"

"I'm much obliged for the fine breakfast you have given me," said Buster in his deepest, most grumbly-rumbly voice. "I've saved a fat trout for you to make up for the one I ate yesterday. I hope we'll go fishing together often."
Then he went off laughing fit to kill himself. Little Joe couldn't find a word to say. He was so surprised and angry that he went off by himself and sulked. And Billy Mink, who had been watching, ate the fat trout.
